Wing Alignment

I'm looking at a Stik that was stick built and the measurement from the wing tip to the tail is off about 3/4 of an inch from one side to the other. WS 71 1/2" Fuse L 66". How will this affect straight and level flight? It seems that it might have a tendency to dip a wing or turn? Thoughts and comments appreciated.

3/16" I could maybe live with on that style plane,, 3/4" is a lot,, you're going to have uneven pressure wanting to yaw that plane and you'll have to counter with opposite rudder trim which will vary with airspeed,,You're going to want to fix that fir sure,,,,

It's an Ugly Stick. If you fly it as intended, it will bore holes in the sky on windy days and be an all around beater plane. On a wing that big, I doubt you'll notice. If it were a pattern or IMAC plane you probably would, or if you plan to fly it that way maybe so, maybe not. Of course, if it's really noticeable or just bothers you, it's simple enough to fix.

How will this affect straight and level flight? Thoughts and comments appreciated.

It depends. If the stik has main-wing-lift, and can fly straight and level without any assistance from the elevator, then you will be just fine. But, when you throttle down and require a little elevator up-trim to maintain level flight, it will fly level, but not straight. It will veer to one side.

If the wing is off center by 3/4", imagine what other surprises are waiting for you? Have someone hold the plane up with the nose pointing at their chest and in a basically level attitude (like it was flying straight). Now, you stand back about 10' from it and eyeball the tail to wing alignment. Does the stab look like it's parallel to the wing? Does the rudder/fin look like it's square to the stab? It's probably crooked as a dog's leg.
